Manchester United have been warned by Roma manager Rudi Garcia that they will need to make a bid of around €100 million (£79million), if they want to secure Kevin Strootman's signature this summer.

The Frenchman had tried to discourage the suitors of the Dutch midfielder earlier as well, insisting that Strootman would remain a Roma player this summer.

But United boss Louis van Gaal has refused to give up the chase, stating that he would be monitoring the midfielder's recovery from injury before making a decision.

And now Garcia, whose side narrowly lost to United in a pre-season friendly game on Saturday, says that Roma will only change their stance on Strootman, if they receive a "three-digit offer" for him.

"What can I say about the rumours (about Strootman joining United).Maybe after a three-digit offer (i.e. 100 million Euros), then we will sit down and think about it," the former Lille boss told Sky News, following his side's friendly against the Red Devils.

Garcia also went on to say that Strootman, who has been out of action since picking up an anterior cruciate ligament injury in March, is soon expected to make a comeback.

"Kevin is following a normal recovery programme. He is fine. He will start running soon," he added.

Meanwhile, Memphis Depay has reportedly been advised by van Gaal to continue with his current club PSV, despite the Red Devils reportedly being interested in securing his signature this summer.

Apart from United, the 20-year-old winger, who turned several heads following his brilliant performances with Netherlands in the 2014 World Cup, is also being heavily linked to Tottenham Hotspur, with new manager Mauricio Pochettino keen to strengthen the Spurs' attack.

The £18 million-rated winger is also reportedly keen to move to England to test his abilities in the Premier League.

But van Gaal, who gave Depay a chance to represent his country in the 2014 World Cup, has reportedly asked him to stay on at PSV for another season.

According to Goal, the Dutchman privately met up with the 20-year-old and told him that remaining with his current club for another season would be beneficial to his career, instead of moving to a new club.

However, it will be interesting to see whether the youngster pays heed to van Gaal's advice or gets tempted by offers from other clubs in the Premier League.
